eurekaclient启动报错

eurekaclient启动报错

在eurake服务端配置 eureka.instance.prefer-ip-address=ture时，客户端需配置eureka.instance.hostname的值；

否则客户端在启动注册时会抛异常，刚开始以为是maven依赖冲突，折腾了好久。

启动异常信息如下：

org.springframework.context.ApplicationContextException: Failed to start bean 'eurekaAutoServiceRegistration'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.eurekaApplicationInfoManager' defined in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.appinfo.ApplicationInfoManager]: Factory method 'eurekaApplicationInfoManager' threw exception; nested exception is java.lang.NullPointerException
